1940 Map of Mescal Creek

About this map

The San Andreas Rift Zone carves a distinct path through this section of the San Gabriel Mountains, creating a rugged geological boundary where the mountains meet the southern edge of the Antelope Valley. In this mid-century landscape, rural life centers on isolated family-named holdings such as Hagenbaugh Ranch and Soules Ranch. The terrain transitions from the high peaks of Pinyon Ridge down into deep incisions like Graham Canyon and Mescal Creek. A network of early desert thoroughfares, including the Pear Blossom Highway and the Llano Cutoff, connects the small settlement of Largo Vista to the broader region. The presence of Caldwell Lake and various springs near the rift zone highlights the critical role of water sources in this arid high-desert environment within the Angeles National Forest.
